Hello. It seems the starter itself is wore out. The solenoid powers the motor but is not 'kicking out' the pinion gear to engage the flywheel; not like it should anyway. The 'whirring' sound is the starter; the 'grinding' sound are the starter and flywheel teeth not 'meshing' right. Remove and replace the starter. Good luck and keep me informed; if you want to.

Same as any other plug gap; 25thou or 0.6mm

If you want to damage the aluminium pistons, head and other parts, the air inlet box is a good place to start.

try a new filter and fluid

There no starter fuse for the starter itself but there fuses for the ignition normaly with a tester oe side to ground any metal part of the car the other end check each side of the fuses

you need to reset by obd for learn the start point

The traction control light in these years is usually a bad wheel speed sensor built into the wheel bearing. Cost around $600. The audio may be as simple as entering the unlock code. The deceleration could be a hundred different things so you'll have to pay to get that diagnosed.

STARTING DISABLED REMOVE KEY Refer to Theft Systems Description and Operation in Theft Deterrent STARTING DISABLED REMOVE KEY The radio illuminates the STARTING DISABLED REMOVE KEY message when the VTD system has disabled the starting system. The radio receives a message from the theft deterrent control module via the serial data circuit requesting illumination. Your best bet ,take it to Cadillac dealer and have it checked . Could have DTC'S - diagnostic trouble codes DTC B1015 DTC B1016 DTC B3031 DTC B3055 DTC B3060 DTC B3090 DTC B3935 DTC B3976 DTC P1629 DTC P1630 DTC P1631 The theft deterrent module or the insturment cluster or the ECM is not seeing correct info. The vehicle theft deterrent (VTD) system functions are provided by the theft deterrent control module. When an ignition key is inserted into the ignition lock cylinder and the ignition is switched ON, the transponder embedded in the head of the key is energized by the exciter coils surrounding the ignition lock cylinder. The energized transponder transmits a signal that contains its unique value, which is received by the theft deterrent control module. The theft deterrent control module then compares this value to a value stored in memory, learned key code. If the value is correct the theft deterrent control module sends a random generated number to the transponder, this is called a challenge. Both the transponder and the theft deterrent control module perform a calculation on the challenge, if the calculations match the theft deterrent control module sends the fuel continue password via the serial data circuit to the Engine control module (ECM). If either the transponders unique value or the calculation to the challenge is incorrect the theft deterrent control module will send the fuel disable password to the ECM via the serial data circuit. The components of the VTD system are as follows: • Theft deterrent control module • Engine control module (ECM) • Ignition key (Transponder) • Ignition lock cylinder • Security indicator

Hey Gary, take your car and get the transmission fluid and filter changed immediately... you will be glad you did...(expensive lessons speaking!!!)

If you REALLY want help, you need to do what you would have to do at ANY auto parts store. The first question is ALWAYS "What are you working on?" Without having to be ASKED, you should ALWAYS VOLUNTEER the following info: MAKE MODEL YEAR TRIM (seires) ENGINE TRANSMISSION

If you pull the windows they will separate from the window channel hardware. If separated there is nothing to keep the window glass held up and it will fall back down. Check your fuses for power windows, there may be more than one. Also check the power window relay(s). The relays may be located under the hood in the fuse box.

Visit the on-line store, know as reliable-store, they have the repair manuals. I'm sure you will get the solution of your problem. Best Manuals

Your dts uses drive by wire. The gas pedal is actually an electrical switch connected to the engine computer which then actuate a throttle body motor which causes the car to speed up or slow down. If you mean the car won't acceleration then the throttle actuator is probably going out, this is common and you replace the throttle body assembly as the actuator is sealed onto it. Had the same problem with my 04 srx (which is mechanically the same as a cts). If you have a check engine light on (and you should) get the codes read first as there are a few other problems that can cause throttle problems, however they are less likely the cause.

Is the motor receiving power? If not you have to check electrical system to locate the place that is not transmitting power. Could be a fuse/relay, switch, bad connection. If the motor is turning and nothing happens then the drive mechanism from motor to sunroof is stripped. Not good.

No. If it was done right, It would have started. If it is an interference engine, leak down test should have been done first.
